[BitcodeReader] Infer the correct runtime preemption for GlobalValue Summary: To allow bitcode built by old compiler to pass the current verifer, BitcodeReader needs to auto infer the correct runtime preemption from linkage and visibility for GlobalValues. Since llvm-6.0 bitcode already contains the new field but can be incorrect in some cases, the attribute needs to be recomputed all the time in BitcodeReader. This will make all the GVs has dso_local marked correctly if read from bitcode, and it should still allow the verifier to catch mistakes in optimization passes. This should fix PR38009.
